WTB Standard TCS Valve 34 Mm Pair Tubeless Tire Bicycle Bike Presta

Valves are tough and do their job with two minor complaints:

Because of the conical rim seat they can end up not quite perpendicular to the rim they hold pressure fine but point away from the rim at a slight diagonal if you're not very careful.

The valve caps thread onto the valve cores themselves not the outer barrel of the valve so it is easy when removing the valve cap to take the valve core out with it! This could be disastrous out on the trail. Every time it has happened to me I realized it in time to get the core back in before losing too much pressure.;

Used this on my new bontrager carbon rim;

Easy to install. Sealed up nicely in my WTB rims against wtb tubeless tape. Not fancy like some but very functional and affordable.;

Got my brand new bike home the other day and the tubeless setup had not sealed on my front tire aired up the tire and broke my valve stem. Ordered these and replaced when they got here worked great and one I got the tire seated and sealed have had no more issues.;

Great product for my dtswiss wheelset!;
